Class
    Foam::totalFlowRateAdvectiveDiffusiveFvPatchScalarField

Description
    This BC is used for species inlets. The diffusion and advection fluxes are
    considered to calculate the inlet value for the species
    The massFluxFraction sets the fraction of the flux of each particular
    species.
